As the title says, I'm wondering what I could do with 2 sheets of 2" thick 8ft x 4ft styrofoam sheeting. It's the white flaky kind. I've already got a temp controlled refrigerator that I ferment in. I don't have a keezer collar yet. That's an idea, but this will only take a bit of the foam. I'm wondering if anyone has other input. I'm an AG brewer if that means anything.
